PATENT OFFICE.

FREDERICK D. LIVINGSTONE, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR OF ONE-IIALF TO ALMON GOLT, OF SAME PLACE.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 338,584, dated March 23I 1886.

Application filed November 18, 1885 To all whom it may concern.-

Be it known that I, FREDERICK D. LIVING- s'roNE, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Sash-Fasteners, of which the following is a specification, reference being had to the accompanying drawings. .A

My invention relates to an improvement in sash-fasteners; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is an elevation of a portion of one of the inner faces of a window-frame, partly in section, the windowsashes being shown in dotted lines. Fig. 2 is a vertical section taken on the line xa' of Fig. zo l. Fig. 3 is a detail View.

A represents a metallic cast-frame, composed of a horizontal central portion, a, and Vertical arms a', one of which extends npwardly from one end of the central portion or body, and the other depends from the opposite end thereof. The outer faces of the body and the arms are on the same Vertical plane. This casting is secured in a Inortise or recess made in the face of the window- 3o frame, the arms of the casting being in ways in which the window-sashes are raised and lowered, the parting-strip Z of the frame being between the two vertical [arms a, as shown in Fig. l.

Transversely in the center ofthe body of the casting works a shaft, B, which may be reciprocated or moved endwise, and has projeeting portions or ends that extend beyond the opposite ends of the central portion or 4o body of the casting or frame. Coiled extensible springs C are on these ends, and bear against the ends of the central portion of the frame A.

That portion of the shaft in the portion a.

of the frame is provided on opposite sides with feathers or webs b b the shaft and the webs forming a key.

From the inner end of the key extends a rod, b2, that is connected to a pivoted handlever, D, on the inner face or side of the window-frame.

E and E represent gear-pinions, that are journaled in the frame A, and have their peripheries projecting through openings in the Serial No. 183,226. (No model.)

arms of the said frame and beyond the faces of the said arms. The web b of the key engages normally with the pinion E and the web b with the pinion E, to prevent the pinions from rotating.

F represents a rack-bar, that is secured on 6o one side of the upper sash, and F represents a similar bar, that is secured on one side of the lower sash. IVith these rack-bars the teeth ofthe pinions engage, and as the said piuions are locked by the endwise-moving key, it follows that neither of the sashes can be raised or lowered by a person on the out side.

Vhen it is desired to lower the upper sash, the lever is moved inwardly, which with- 7o draws the web b of the key from the pinion E, which frees the said pinion, and as the upper sash is lowered causes it to rotate. Vhen the sash is lowered to the desired point, the lever is released, and the web b again locks the pinion E and securely fastens the sash. The operation of the lower sash and its operating-pinion is precisely the same, and it will be understood that both sashes will be locked in any position, whether raised or low- 8o ered.

Having thus described l my invention, I claiml. The combination of the casting, the gearpinions `iournaled therein, for meshing with the rack-bars with which the window-sashes are provided` and the endwisc-movable shaft having the feathers engaging with the pinions, whereby either of the pinions may be disengaged by moving the shaft, substantially 9o as described.

2. The combination ofthe casting, the pinions journaled therein, for meshing with the raekbars secured to the window-sashes, the endwisc-movable locking-shaft having the feathers for engaging the pinions, whereby either of the pinions may be disengaged by moving the shaft, and the springs for keeping the feathers of the shaft normally engaged with both pinions, substantially as described.

In testimony that I ela-im the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.

FREDERICK D. LIVINGSTONE.
